Considering selling. Talk me into/out of it.

I have an old school DMPS LR308 chambered in 6.5 Creedmoor. I bought it from a local shop, and a few weeks later they had the Unitah Precision https://uintahprecision.com/product/upr10/ that just absolutely had to have been a companion to my LR308 (meaning likely the same consigner / prior owner). It was a novelty purchase for me - I'm a bigger guy but the weight, the cost of ammo, the inherent inaccuracy vs a bolt gun, and the fact that I'm east of the Pecos with very few places to stretch my baby's legs properly have led me to consider selling it.

Should I just keep her as a vault vixen? She shoots beautifully and is a no-fuss kinda gal. But every old lady needs maintenance and love, and I feel like I'm letting her down. Help!
